The RX anchor is ideal for universal application on all kind of materials. The expansion of the plug takes place on four sectors through compression of the same in the hole, this in case of compact materials; otherwise with hollow materials or interspaces the screw draws the plug which creates a "knob" within the cavity, ensuring therefore a strong hold.
The edge (collar) on the body of the anchor prevents it to enter inside the hole causing an incorrect expansion and avoids as well any tension on the coating materials.
